PERSONALITY (2)
set the process execution domain
SYNOPSIS
int personality(unsigned long persona );
DESCRIPTION
Linux supports different execution domains, or personalities, for each
process. Among other things, execution domains tell Linux how to map
signal numbers into signal actions. The execution domain system allows
Linux to provide limited support for binaries compiled under other
Unix-like operating systems.
personality
will make the execution domain referenced by
persona
the new execution domain of the current process.
RETURN VALUE
On success,
persona
is made the new execution domain and the previous
persona
is returned. On error, -1 is returned, and
errno
is set appropriately.
ERRORS
EINVAL
persona
does not refer to a valid execution domain.
FILES
/usr/include/linux/personality.h
CONFORMING TO
personality
is Linux-specific and should not be used in programs intended to be portable.
